whats a 4 letter word for dry toast

A 4 letter word for "Dry Toast" is Rusk.

A rusk is a type of biscuit which can be made one of several ways. One is to first bake the dough that you've let rise, slice it up, then bake the slices until they're dry. Some people like to make rusk to use as a baby teething food.

The rusk is also a popular treat in Britain, starting out as a way for sailors to preserve carbohydrates. In early June of 2012 the Great British Biscuit Festival was held in London.

Here's an example Rusk recipe that demonstrates another way to make it, if you'd care to give it a try:

• 2C unbleached white flour
  2C whole wheat flour (coarsely ground)
  1/3C sugar
  1/2tsp salt
  2tsp baking powder
  1tsp cinnamon
  1/2C melted butter
  2 eggs
  3/4C buttermilk
  2tsp pure vanilla extract
  2tsp almond extract
  

Preheat your oven to 400°F while you combine all the dry ingredients. Next combine all the wet ingredients and pour them into the bowl holding the dry ingredients, stirring until you've created a soft dough. Roll the dough out on a floured surface and flatten to about half an inch thick, then cut into rectangles of 2" x 4". Bake the squares for about 25 minutes. Once the tops are brown and crispy, pile them onto a baking sheet and keep them in a 200°F oven all day, or over night (about 12 hours).
